Climate change, wildlife conservation, deforestation, ozone depletion, air pollution, water pollution, land degradation -- the list of environmental challenges, the root cause of which is human interaction with the Earth, is long and daunting. Earth Day is a time when we all take notice of these problems, and try to do our part to clean up the mess we all are responsible for making.
Some ideas to help the planet are simple, sensible and easy to do, like walking instead of driving when possible, taking using bags to the store, or recycling.
There are other ways to aid the environment that are expensive, complicated and occasionally downright crazy. This special Earth Day slideshow is dedicated to the latter.
